She's just being a bitch. People like her can't accept the fact that the ones she idolized was taken from her, she doesn't have anything better to do but to spread humors and love over the people who suffered by those. It's scary to think about how they would try to ruin someone just for there sake of pride. And the way she was cooked and threatened made her lose her temper, she can't really accept that fact that the person who she tries to idolized and befriend with ( and for her benefits ) threatened her.
